What are the causes of sinus infection and how can it be treated? - #16759

I’ve been dealing with sinus issues for as long as I can remember, but recently, it’s been getting worse. I often have a stuffy nose, headaches, and sometimes facial pain, especially around my eyes. The worst part is that I get this thick nasal discharge that won’t go away, and it’s been lasting for over a week now. I’ve gone to the doctor, and they said it might be a sinus infection, but I’m still not entirely sure what causes these infections and how to treat them properly. From what I’ve gathered, sinus infections happen when the sinuses get inflamed or blocked, but I’m curious to know more about the exact causes. Could it be allergies or a cold that triggered this, or is there something else going on? I’ve also read that bacteria or fungi can cause sinus infections, but how do doctors figure out what the cause is? I’ve been given antibiotics for sinus infections before, but I’m not sure if they’re always necessary. How can you tell if a sinus infection is viral, bacterial, or fungal? I’ve tried using saline nasal sprays, drinking warm fluids, and even taking over-the-counter decongestants, but nothing seems to provide lasting relief. I’ve heard that some people use Ayurvedic remedies or essential oils to help clear up sinus infections, but I’m unsure if they work. Are there natural treatments that can help reduce inflammation or clear the sinuses without medication? I’d really like to avoid relying on antibiotics if I don’t have to. Lastly, I’m curious about how long a sinus infection lasts and when I should see a doctor again if it doesn’t improve. Are there complications to watch out for if a sinus infection lingers for too long, or is it typically a self-limiting condition?
